HENRY VINTER, OF IIONESDALE, PENNSYLVANIA.

MACHINE FOR TURNING UMBRELLA HOOKS OR HANDLES.

T0 all whom it may concern.-

Be it known that I, HENRY WINTER, ot' Honesdale, in the county of Wayneand State of Pennsylvania, have invented, made, and applied to useacertain new and Improved Means for Turning Umbrella-Hooks, Sto.; and Ido hereby declare the following to be a full, clear, and exactdescription of my said invention, reference being had to the annexeddrawings, making part of this specitication, wherein- Figure lis a planof my turning apparatus. Fig. 2 is an elevation ot the same, and Fig. 3is a cross-section.

Similar marks of reference denote the same parts.

Straight sticks for umbrella-handles, parasol-handles, Src., haveheretofore been turned by a hollow revolving mandrel, carrying a cutteror cutters, but such machinery is not adapted to turning the hooks andbends usually made on the ends of such handles.

The nature of my said invention consists in a revolving head sustainedin a peculiar manner and. carrying a cutter, and said head is formed sothat the bent or hooked part of the stick can be turned around and drawnthrough said head as the stick itself is swung over from one side to theother. Thereby all parts of the hook or bend of thel stick are dressedperfectly round and true, making a neat and handsome finish with butlittle labor.

In the drawings, a is a ring-shaped stock secured by the liange b in anyconvenient position. c is a ring-shaped cap setting within .a recess inthe stock a., and d d are screws retaining said cap to the stock. Theconstruction ot' this cap and stock are such that there is an open spaceleft between them, and the rings themselves are notched entirely throughon one side, for a purpose hereinafter shown.

Between the stock a and cap c, I introduce the cutter-head e, that ismade with circular ribs at its edges entering vcircular grooves in thefaces of the respective parts a and c, as seen att' i, Fig. 3. Aroundthe periphery ot' this cutter-head e is a groove for receiving the bandor belt f, by which it is rotated at a high speed, the said head turningin the space formed for it between a and c, as aforesaid. This belt fpasses out at openings through the stock a, and is driven by competentpower applied to a drum or wheel. In this head e is a cutter, g, ot' asemicircular or gouge shape, secured by a screw, and h is a mouth formedin the cutter-head for the chips and shavings to escape as cut from thestick that is entered through the circular hole in the center ot' thisrevolving cutter-head. The cutter-head around this center hole isbeveled ott' or formed ot' nearly a semicircuiar shape, as seen in Fig.3, so as to flare or be trumpetshaped on each side.

k is a fence or support sustained by the arms l and screws m, and saidfence can be adjusted so that one side thereof comes on the line of thecircular hole in the center ot e, and n is a gage on the face ot' thefence lr. I prefer that the sticks themselves should be dressed oit', sofar as straight,by the ordinary hollow mandrel, although this apparatusmay be used for that purpose. The stick is laid in the angle formedbetween 7c and n, and passed through the revolving cutter-head, and oncoming to the part of said stick that is hooked or bent, the attendantswings the stick over as he draws the hook through the cutter-head,thereby causing said' cutter-head to dress the hook or bend circularly,While the curvature in the outline ot' such hook or bend is followedwith precision. The fence k becomes a support to the hook or bend whilebeing dressed, and prevents vibration in the saine.

What I claim, and desire to secure by Letters Patent, is A 1. Therevolving cutter-head with a gougeshaped cutter, and with a centeropening that is flaring or trumpet-mouthed on each side for dressingcurves or hooks on umbrellasticks and other articles, substantially asspecied.

2. The mode of constructing the stock a and cap c for receiving andsustaining the rotating cutter-head, as set forth.

3. The adjustable fence la, in combination with the revolvingcutter-head e, for the purposes and as specified.

In witness whereof I have hereunto set my signature this 16th day ofMay, 1868.

HENRY WINTER.
